Tomography of Feshbach resonance states [PDF]

Science, 2023
Feshbach resonances are fundamental to interparticle interactions and become particularly important in cold collisions with atoms, ions, and molecules.

Polaritonic Feshbach resonance [PDF]

Nature Physics, 2014
A Feshbach resonance occurs when the energy of two interacting free particles comes into resonance with a molecular bound state. When approaching this resonance, marked changes in the interaction strength between the particles can arise.

Polaritonic Cross Feshbach Resonance [PDF]

Physical Review Letters, 2019
We demonstrate the existence of a cross Feshbach resonance by strongly driving a lower polariton mode and by monitoring in time the transmission of a short optical pulse at the energy of the upper polariton mode in a semiconductor microcavity.

Feshbach spectroscopy of a shape resonance [PDF]

Physical Review A, 2005
The authors present a spectroscopy technique for studying cold-collision properties. The technique is based on the association and dissociation of ultracold molecules using a magnetically tunable Feshbach resonance.

Phase protection of Fano-Feshbach resonances [PDF]

Nature Communications, 2020
The lifetime of decaying quantum states has been thought to depend on the strength of the coupling causing the decay. Here the authors demonstrate that quantum mechanical interference can dominate this process, observing Fano-Feshbach resonance lifetimes

Feshbach resonance management for Bose-Einstein condensates

Physical Review Letters, 2003
An experimentally realizable scheme of periodic sign-changing modulation of the scattering length is proposed for Bose-Einstein condensates similar to dispersion-management schemes in fiber optics.

Broad Feshbach resonance in the 6Li-40K mixture [PDF]

Physical review letters, 2010
We study the widths of interspecies Feshbach resonances in a mixture of the fermionic quantum gases 6Li and 40K. We develop a model to calculate the width and position of all available Feshbach resonances for a system.

Feshbach resonances in ultracold gases [PDF]

Reviews of Modern Physics, 2010
Feshbach resonances are the essential tool to control the interaction between atoms in ultracold quantum gases. They have found numerous experimental applications, opening up the way to important breakthroughs. This Review broadly covers the phenomenon of Feshbach resonances in ultracold gases and their main applications.
